The Opportunity rover, still crawling around Mars after surviving a potentially deadly dust storm this summer, is starting a trip into the Victoria crater.

There’s an interesting band of rocks 40 feet down from the rim of the half-mile-wide crater, and engineers plan to slowly pilot the robot down to that spot. NASA has said this latest mission is a risky one, but worth the potential science payoff. And considering that the rover, originally slated to last for 90 days, has already been tooling around for 1,291 Martian days, or sols, they might as well take the chance.—Gregory Mone
